RNA polymerase - ANSWER pries the two strands of DNA apart and joins the RNA nucleotides as they base-pair along the DNA templates promoter - ANSWER DNA sequence where RNA polymerase attaches and initiates transcription Synthesis of RNA transcript - ANSWER initiation; elongation; termination synthesis of RNA transcript initiation - ANSWER after RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point of the template stra...

5′ cap - A modified form of guanine nucleotide added onto the 5′ end of a pre-mRNA molecule. A site - One of a ribosome's three binding sites for tRNA during translation. The A site holds the tRNA carrying the next amino acid to be added to the polypeptide chain. (A stands for aminoacyl tRNA.)
